Known in popular circles as the iPhone 6S, the new flagship will also contain a 2GB RAM and a 12MP primary camera, along with the Force Touch input that was introduced in the new MacBook in March.

The rose gold colour isn't new to Apple's devices, having been introduced with the iPhone 5S back in 2013. It seems the iPhone 6S could sport a similar look, albeit with a larger frame.

The Force Touch option will also be revolutionary in terms of smartphone technology. It's operability was revealed by Apple's patent application published in April this year. Thanks for Force Touch, The iPhone will display different inputs based on how hard you press the screen.

"Force Touch can enrich user experience due to more input methods and support of handwritten signatures, which is beneficial for expanding the commercial market," Kuo said.

He also added that the iPhone 6S will be built using Series 7000 aluminum, a material 60 per cent stronger than the one used on the iPhone 6 and the 6 Plus. This could be in response to the 'bendgate' problems soon after the two devices were released in September last year. The glass component in select models could also feature Sapphire glass instead of the universal Gorilla glass.

TouchID is another feature of the iPhone 6 that could expect an upgrade with a view to strengthen the Apple Pay system which has been drawn into an intense competition for wireless payment options by Android gadgets.

The upcoming A9 processor may also be introduced with the iPhone 6S, and will contain an unprecedented 2GB RAM as compared to the 1GB RAM used presently.

Even though Kuo has been rather accurate with his Apple-related leaks so far, if these features do appear in the next iPhone, we won't really be too surprized as Apple has the technology and the means available to bring these to fruition in the upcoming device.
